Abstract: An electrolytic capacitor includes a capacitor element, an exterior body covering the capacitor element, an anode terminal electrically connected to an anode body of the capacitor element, and a cathode terminal electrically connected to a cathode portion of the capacitor element. Each of the anode terminal and the cathode terminal includes a connection portion in contact with the capacitor element, a lead-out portion led out from the connection portion to an outer surface of the exterior body, and an external terminal portion disposed along the outer surface of the external body and having an exposed surface exposed from the external body. At least a part of a covered portion of the lead-out portion, the covered portion being covered with the exterior body, has a cross-sectional shape including a chamfered shape corner portion in a cross section parallel to a surface region of the outer surface of the exterior body where the lead-out portion is led out.

Abstract: A reactor includes a coil body, an exterior case, and a filler. The coil body includes a core and a coil wound around the core. The exterior case includes a metal structure and a resin frame. The metal structure has a bottom surface and a side wall provided to stand upright from the bottom surface. The bottom surface and the side wall of the metal structure are unitarily formed with each other. The frame is disposed at an opposite side to the bottom surface of the metal structure. The exterior case houses the core and the coil. The filler is filled between the exterior case and the coil body.
